Please follow the below steps:
1. After connecting to Wi-Fi successfully, please stay within a reasonable distance of the Wi-Fi to avoid automatic disconnection caused by the weak network signal.
2. When too many devices are connected to the same Wi-Fi network, automatic disconnection may occur.
3. If you use a metal protective case, please remove the protective case and try again.
4. Please turn off the Wi-Fi and turn it on again to check again.
5. Try to use another Wi-Fi network
If the issue persists, contact the Nothing Support Team for further assistance.
